ELM327 Wi-Fi OBD2 Diagnostic Adapter for Compatible Apps

View supported engine data on a compatible device before deciding what to investigate. This ELM327-style Wi-Fi adapter plugs into a suitable OBD2 vehicle and works through matching diagnostic software. It is for owners who already have, or can obtain, a compatible app and host device.

• ✅ Start an engine-light investigation — Read supported fault codes through a compatible app instead of guessing from the warning alone.
• ✅ View data on your device — The wireless link lets matching software display the engine information the vehicle provides.
• ✅ Check a reading over time — Use available live data in the app when comparing a supported parameter during diagnosis.
• ✅ Keep the adapter compact — The plug-in body fits directly at the compatible diagnostic connector without a separate handheld display.

Use the app to understand the recorded code

This is an adapter rather than a scanner with its own screen. The selected ELM327 black version is pictured with Wi-Fi connectivity, and it needs diagnostic software that matches both the adapter and the host device. Do not assume Bluetooth-only apps will pair with it.

Vehicle protocol support and the chosen app determine which data and functions are available. Reading or clearing an engine code does not diagnose every vehicle system, repair a fault or guarantee that a warning will stay off.

One adapter is supplied. The phone/tablet/computer and diagnostic software are separate; a free app or paid licence is not confirmed as included. Check the vehicle, app and connection requirements together before ordering.

Use matching diagnostic software to interpret the engine information made available by the vehicle.

The pictured ELM327 adapter uses Wi-Fi; check app connection requirements before ordering.

A compatible app and host device are separate requirements, not package contents.

Allow room around the vehicle's diagnostic port for the adapter body.

Clearing a code does not repair its underlying cause.

Check the actual vehicle protocol rather than assuming all model years are compatible.

App features vary; the adapter alone does not provide every pictured analysis function.

The host app provides the display and controls for supported diagnostic functions.
